Description

Peroxidemodifiedpolypropyleneglycol CAS NO 52309-41-8 is a specialized polyether polyol derivative, chemically modified with peroxide groups to introduce reactive functionalities. This modification is critical for enhancing polymer cross-linking efficiency and improving final material properties such as adhesion, toughness, and thermal stability. It is an essential intermediate for formulators and manufacturers in the polymer, coatings, and adhesives industries seeking to develop high-performance, customized materials.

Application

• As a reactive polyol component in the synthesis of polyurethane (PU) foams and elastomers, improving cross-link density and mechanical properties.
• As a cross-linking agent and adhesion promoter in high-performance coatings, sealants, and adhesives.
• As a modifier in epoxy resin systems to enhance flexibility, impact resistance, and chemical durability.
• In the production of composite materials to improve interfacial bonding between fibers and polymer matrices.
• As a key intermediate for creating specialty surfactants and dispersants with unique surface-active properties.
• In rubber processing as a co-agent to improve vulcanization efficiency and aging resistance.

Quality Control

Our Peroxidemodifiedpolypropyleneglycol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, functionality, and performance. Key parameters such as peroxide value, hydroxyl number, and molecular weight distribution are monitored. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended. Keep away from heat, sparks, open flames, and incompatible materials such as strong reducing agents.
